In thefold at l5 merels inserted e bottom nism `of the roller shade I 2.The roller thus arranged constantly urges the shade to a. fully rolledand raised position. The stick or cross 55 member 24 is encountered bydoweistick I 3 howfer to use black pressed paper stock for the channelssince these channels 21 and 28 may be originally placed around therolledup shade to serve as a container package 'and thus largelyeliminate the individual wrapping materials for the shades in handlingand shipping. 'Ihe channels 28 are made in several sections each, whichsections may be about the same length as channel 21. The finishedpackage, as shown in Fig. 3, is held secure by a few strips of adhesivetape 3|. A degree of mutual protection against lcrushing is lafforded bythe shade and the channel members when thus packaged.

The selection of materials and the specic ar- I rangement of parts willbe understood to be subject to some variation in order to accommodatethe -window fixture of the invention to Various types of windows, allwithin the spirit of this invention and the scope of the appendedclaims.

The operation of the device is readily understood. If, during theenforceddarkening of a community, the user desires to illuminate a roomwithout sacricing the advantages of ventilation, the window is openedbefore pulling the shade. Then the bottom dowel stick I6 of the shade isengaged beneath hooks 30 andthe spring shade roller holds both panelstaut while. stick .lj and cross member 24 keep the panels spaced to forma sort of Ventilating flue between them.J When the shade is rolled up,the outermost web rolls roller, a bottom stick between the panels at thebottoms thereof and a cross member extending freely between the panelsin parallelism with the roller whereby the panels are Vspaced when theshade is drawn, said panels having staggered Ventilating openingstherein precluding passage yof* light through the shade.

4. In a Ventilating blackout window shade and y package therefor thecombination of a roller shade comprising a roller and two superposedpanels secured to the roller, a cross member passing between the panelsand adapted for fixed mounting in parallelism with the roller forspacing the panels, a bottom stick spacing the panels at `the bottom,and a plurality of elongated channel vshaped members serving selectivelyas the principal packaging members for the shade and as top and sideshields to embrace the top and sides of the shade in use.

5. In a Ventilating blackout roller shade the combination of a shaderoller, a pair of superposed panels secured to the roller at the topedges, means for spacing the panels at the bottom, and means adapted tobe fixed in substantial parallelism with the roller for spacing the Ypanels intermediate the top andr bottom edges thereof.

6. In a Ventilating' blackout roller shade the combination of a shaderoller, a pair of superposed panels secured `to the roller at the topedges, means between the panels for spacing them at the bottom, meansadapted to be fixed in substantial parallelism with the roller forspacing the panels intermediate the top and bottom edges thereof, andchannel .shaped members adapted for mountingabout a window opening forembracing the top and side edges of the shade to preclude passage oflight rays and'perrnit the f flow of airybetween the panels.

up to a greater extent than the innermost web j and the fold or grooveat l5 likewise shifts. The bottom dowel stick is free to accommodatethis movement of the webs during such raising and lowering movement ofthe shade.

What is claimed is:

1. In a Ventilating blackout fixture for' a window, channel members xedaboutthe top and sides of the window, a shade roller mounted within thetop channel, a fixed cross member Aparallel with the shade roller belowsaid roller, a pair of shade panels fixed in superposed relation on saidroller and passing on opposite sides of the xed cross member, a bottomfree roller stick disposed between the panels and vmeans for releasablyengaging said bottom stick when the shade is in fully lowered position.

' 2. In a Ventilating blackout window shade the combination of 'a shaderoller, a pair of superposed panels secured at the tops thereof to saidroller, a bottom dowel stick between the panels at the bottom of theshade and a cross member extending freely between the panels inparallelism with the roller whereby the panels are spaced when the shadeis drawn- 3. In a Ventilating blackout window shade the combination of ashade roller, a pair of super- 4posed panels secured at the tops thereofto said 7. In a Ventilating blackout roller shade the combination of ashade roller, a pair of superposed panels secured to the roller at theAtop edges,`means between the panels for spacing them at the bottom,means' adapted t0 be fixed in substantial parallelism with the rollerlfor spacing the panels intermediate the top and bottom edges thereof,land, channel shaped members adapted for mounting about a windowropening for embracing the top and side edges of theshade to precludepassage of light rays and permit the now of air between the panels, saidpanels having non-registering Ventilating apertures therein. Y

8. In a Ventilating blackout roller shade a spring shadefroller, a shadeweb folded intermediate its ends and havingl coinciding ends secured tothe said `roller whereby a front panel and a rear panel are formed, saidpanels having non-registering Ventilating openings, a cross memberpassing between the panels and adapted to` be fixedly mounted inparallelism With the*v roller for Yspacing the panels, a loose dowelmemberV resting in the fold of the shade web and. serving as a bottomstick for spacing the panels at the bottom ,ofv the shade, disc memberson the dowel member limiting endwise movement thereof in the said foldand means to releasably hold the free ends of the dowel member forretaining the panels taut against the pull of the spring` shade roller.
